Used as a key intermediate in the synthesis of herbicidal compounds, particularly in the development of selective broadleaf herbicides. It exhibits strong activity in controlling weed growth in cereal crops by inhibiting specific enzymes involved in plant amino acid synthesis. Its structure allows for easy modification, making it valuable in agrochemical research for designing new pyridazine-based plant growth regulators. Also investigated for use in crop protection formulations due to its stability and targeted mode of action.
